A mysterious sound with a long history
Hey I love this tracing of lineage, but I think you skipped one crucial link in between postpunk and the illbient era - namely the late 80s, very early 90s stuff that was happening in between the back rooms of acid house culture, experimental hip hop and the squat/traveller community... I've idly called it "drug dub" in the past - though that might be a bit flippant, it was a very LSD-drenched area...
Thanks for the introduction to HOLY TONGUE...this sound is right up my alley, and I love everything that I am currently checking out from their label imprint. Killer article!
